SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Tegra20: Move some include files to arch-tegra for sharing with Tegra30 The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

tegra: Implement gpio_early_init() on Tamonten The PI4 GPIO is used on Tamonten to reset carrier board peripherals. Power sequencing hardware on the carrier pulls the reset low before powering up the Tegra, and the CPU is supposed to signal readiness, and therefore bring peripherals out of reset by pulling PI4 high.

mmc: move more driver config options to Kconfig Move (and rename) the following CONFIG options to Kconfig: CONFIG_DAVINCI_MMC (renamed to CONFIG_MMC_DAVINCI) CONFIG_OMAP_HSMMC (renamed to CONFIG_MMC_OMAP_HS) CONFIG_MXC_MMC (renamed to CONFIG_MMC_MXC) CONFIG_MXS_MMC (renamed to CONFIG_MMC_MXS) CONFIG_TEGRA_MMC (renamed to CONFIG_MMC_SDHCI_TEGRA) CONFIG_SUNXI_MMC (renamed to CONFIG_MMC_SUNXI) They are the same option names as used in Linux. This commit was created as follows: [1] Rename the options with the following command: find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \ -type f -print | xargs sed -i -e ' s/CONFIG_DAVINCI_MMC/CONFIG_MMC_DAVINCI/g s/CONFIG_OMAP_HSMMC/CONFIG_MMC_OMAP_HS/g s/CONFIG_MXC_MMC/CONFIG_MMC_MXC/g s/CONFIG_MXS_MMC/CONFIG_MMC_MXS/g s/CONFIG_TEGRA_MMC/CONFIG_MMC_SDHCI_TEGRA/g s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g ' [2] Commit the changes [3] Create entries in driver/mmc/Kconfig. (copied from Linux) [4] Move the options with the following command tools/moveconfig.py -y -r HEAD \ MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI [5] Sort and align drivers/mmc/Makefile for readability Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Marek Vasut <marex@denx.de>
